Diane Keaton Cause of Death: How She Fought Cancer Twice, 'Rapidly Lost Weight' in Weeks Before Her Death — Diane Keaton, Who Fought Cancer Twice, ‘Rapidly Lost Weight’ in Weeks Before Her Death

The beloved American actress, Diane Keaton, who played the role in Annie Hall, The Godfather, Father of the Bride, and numerous other movies, passed away on the 11th of October, 2025, when she was 79 years old. Her family requested privacy, and no official cause of death has been announced in public yet.

In a long acting career, she was not only respected because of her acting but also her personal style, sense of humour, gender sincerity and her personal challenges that she was brave to talk about including an eating disorder in her younger days.

During the few weeks before her death, close friends observed a physical transformation of dramatic nature. Singer songwriter, longtime friend, Carole Bayer Sager, said that she last saw Keaton two or three weeks ago, and that she was very thin. She had been appalled at the extent to which Keaton had lost weight during that brief period, and said the loss was serious and unanticipated. Nevertheless, she was still observed to be bright spirited by people who observed her, and thus still, she was still happy and upbeat, creative, observant and even taking photos around her.

Cancer Amongst Women and Its Relation To The Loss of Weight

Many Cancers that are common and exist in women. Some of the most common forms of cancers associated with women include breast cancer, cervical cancer, ovarian cancer, and uterine endometrial cancer. Early diagnosis in such cases is very important to track before something worsens.

Early Signs & Symptoms

Most cancerous conditions among women are not dramatic at an earlier stage and those that do manifest are unnoticed.

Alterations of the breast tissue which comes with lump, dimpling of the skin, discharge or alteration of shape.

Abnormal bleeding happens like vaginal bleeding not during the normal cycle, or following menopause.

Such signs as pelvic pain or chronic bloatingmay indicate ovarian cancer.

Inappropriate bowel or urinary perforations

Constant tiring, loss of appetite

One of the more frightening symptoms is unexplainable weight loss, which occurs whether this is done deliberately through dieting or through more vigorous exercise.

The causes of weight loss in cancer

In cancer, unintentional weight loss is not merely a cosmetic or a secondary problem but is, in most cases indicative of significant changes within the body. Some of the reasons include:

Reduced appetite

It is because of the tumour itself, or the systemic response hormones, inflammation that lessens the appetite.

Metabolic alterations

Cancers may cause an elevation in Basal Metabolic rate which means the energy that the body uses at rest and more energy is burnt despite lack of additional activity.

Malabsorption Of Nutrients

If the nutrients are not absorbed or gastrointestinal symptoms include nausea, vomiting, diarrhea, pain during food intake that decrease the volume of food that the body can absorb or withstand.

What Women Should Do

When a woman realises that she is losing her weight even without effort, more so then you must consider seeing a doctor.
Watch out other symptoms that occur along with them which includes changes in appetite, fatigue, changes in the digestive tract, pain or swelling.
Routine checkups ,mammograms, HPV tests are crucial and they are able to diagnose cancers before the loss of weight or other serious symptoms set in.
Cancer risk is also minimised by lifestyle issues diet, physical activity, avoidance of smoking, skin protection and alcohol intake.

In the case of Diane Keaton, although they said in the news that she had a previous fight with skin cancer and had difficulties in her eating disorder, could the weight loss at such a rapid pace before death could be connected to a relapse or to some other severe disease? it is not confirmed. However, her story provides us with the understanding that dramatic weight loss is usually a thing that people tend to notice in the last stage of the life of a particular person, and that friends or relatives may notice the changes even when the person does not disclose everything.

The sudden, unexplainable, or rapid weight loss may be a very early indication that something is seriously going wrong. In the case of a woman, it can be a big difference to be mindful of the body, to report to the doctor about the changes, and to actually integrate symptoms instead of ignoring them.
